I knew of a great chat group that was really helpful with old Honda bikes. I had it book marked and went to get the address when I read your post, and the site had been parked! Sorry. I would do as many google searches on your bike and old Hondas until you find something useful. If you need to find parts for your bike, I do have a great site for that! You can order about any OEM part, even one that old! (I know cause I ordered a bunch of crap for my 81 Custom)
